The web-based International WWER Radioactive Waste Operations Benchmarking System (BMS) provides a platform for collecting, analysing and comparing operational waste management data from WWER-type nuclear power plants. It supports Member States in improving radioactive waste management performance and identifying opportunities for waste minimization through benchmarking.
The BMS database (https://nucleus.iaea.org/wwer/ ) enables participating organizations to submit and access data, generate benchmarking reports and evaluate trends in key parameters. Annual data collection allows users to assess performance, identify deviations, and recognize achievements, thereby promoting evidence-based decision-making and cooperation among organizations operating WWER-type reactors.
Objectives
The meeting will provide a forum for participating Member States to review progress in the use of the BMS, exchange operational experience and lessons learned, and discuss approaches to waste minimization and optimization. It will also consider how benchmarking results can inform management decisions, investment planning and regulatory dialogue.
The meeting will address:
-
Presentation and discussion of national (or plant) BMS reports and data consistency;
-
Review of waste streams generated during operation and maintenance of WWER plants, including trends and influencing factors;
-
Methods and technologies for waste optimization and minimization;
-
Use of benchmarking reports and performance indicators for planning and decision-making; and
-
Opportunities for enhancing collaboration and long-term sustainability of the BMS.
A limited number of grants are available to support the attendance of selected participants provided that, in the IAEA’s view, the participant will make an important contribution to the event. There is no registration fee.
In order to be designated by an IAEA Member State or invited organization, participants are requested to submit their application via the InTouch+ platform by 11 May 2026.
